Abstract：Aiming at quick over-the-shoulder launch implementation for air-to-air missiles, a novel launch strategy namely poststall re-orientation is proposed, which uses over stall maneuver of missiles at high angle of attack to re-orientate rapidly. The kinetic and aerodynamic characteristics of a slender missile with relaxed static stability design is calculated by solving unsteady RANS equations coupled with RBD equations, and unsteady RANS equations are discretized under the framework of finite-difference method on moving overset grids. The influence of preset deflection angle of rudders, ejection angular velocity and direct force control on the trajectory and attitude of the missile in overturning is investigated. Finally, a launching strategy combining preset rudder deflection and direct force control is proposed to realize re-orientation of missiles in 1.5 s, which presents valuable guidelines for fast backward-firing of air-to-air missiles.
